    Abstract: One embodiment of the present invention is an integrated circuit implementing a storage-shelf router (1102), used in combination with path controller cards (1110) and optionally with other storage-shelf routers (1104), to interconnect SA' disks (1108) within a storage shelf (1100) or disk array to a high-bandwidth communications medium, such as an FC arbitrated loop (1008). When two, four, six, or eight or more storage-shelf routers are used within a storage shelf, and tl interconnections between the storage-shelf routers, disk drives, and external communications media are properly designed and configured, the resulting storage shelf constitutes a discrete, highly-available component that may be included in a disk array or in other types of electronic devices. The storage-shelf router features a disk-drive adaptation layer (3604) that allows a storage-shelf router to interface to, and manage, any of many different types of disk drives (3608-3611). The disk-drive adaptation layer includes a disk-profile table (3902) and associated firmware logic.

    Abstract translation: 本发明的一个实施例是实现与路径控制卡（1110）和可选地与其他存储架子路由器（1104）组合使用的存储架子路由器（1102）的集成电路，以将SA'盘（1108） 在存储架（1100）或磁盘阵列内的高带宽通信介质（例如FC仲裁循环（1008））中。 当在存储架内使用两个，四个，六个或八个或更多存储架空路由器时，存储架路由器，磁盘驱动器和外部通信介质之间的t1互连被适当地设计和配置，所得到的存储架构成 可以包括在磁盘阵列或其他类型的电子设备中的离散的，高度可用的组件。 存储架式路由器具有磁盘驱动器适配层（3604），允许存储架子路由器接口并管理许多不同类型的磁盘驱动器（3608-3611）。 磁盘驱动器适配层包括磁盘配置表（3902）和相关联的固件逻辑。
